It would be easier that looking at a profile for "de"vouchesThis forum currently only has ratings... stop freaking thinking of ratings as rep. I've seen you say that so many times and tried to correct you each time.
Also no there shouldn't be a negative rating due to the simple fact how many people would "abuse" it.
HmAs stated above, this would most likely be heavily abused. The ratings shouldn't be modified. Like ever.
Every modification makes one group happy, and the other group sad.
